how to update mydiv with ajax and no refresh page

Because there will be a server request either way, and more importantly because video code added to a page more than once or removed from a page even once can confuse some browsers (they may go on playing the sound for instance, even though the player code has been overwritten or removed), I'd say stick with what you've got.

However, if you did want to pursue it, you would use the onsubmit event of the form along with an AJAX routine adequate to the purpose.
